Technical Field

[0001] This utility model relates to the field of liquid flow guidance, and in particular to a liquid flow guidance structure that improves the uniformity of phosphating film thickness. Background Technology

[0002] Improving the uniformity of phosphating film thickness is a key technical challenge in metal surface treatment. Uneven phosphating film can lead to problems such as poor coating adhesion, reduced corrosion resistance, and appearance defects. As a key design element in phosphating tanks or spray systems, the liquid flow guiding structure can significantly improve film thickness uniformity by optimizing the flow state of the treatment liquid on the workpiece surface.

[0003] Patent application CN219315287U discloses a high-performance PTFE impregnation tank for producing PTFE impregnated felt. By adding the impregnation solution into the impregnation tank and simultaneously turning on the second motor, a set of shafts connected to it rotates. Driven by the shafts, the collar drives the stirring rods to rotate, thus stirring the impregnation solution. In addition, four sets of pulleys and three sets of connecting belts can drive other stirring rods to rotate, thereby agitating the impregnation solution during the impregnation of PTFE impregnated felt.

[0004] The existing technology has low impregnation fluidity, which affects the uniformity of film thickness after impregnation.

The outlet guide plate 2 and the spray assembly 3 are located on the same side of the impregnation tank 1. The outlet guide plate 2 is positioned in the spray direction of the spray assembly 3 to guide the flow of the sprayed liquid. The aeration structure 4 is located at the bottom of the impregnation tank 1 and generates gentle convection through microporous aeration, improving the fluidity of the liquid in the impregnation tank 1. The device sets the outlet guide plate 2, the spray assembly 3, and the aeration structure 4 in the impregnation tank 1. The outlet guide plate 2 guides the flow of the liquid sprayed by the spray assembly 3, and the aeration structure 4 generates gentle convection through microporous aeration, improving the fluidity of the liquid in the tank. A mixing structure 6 is also included, which can eliminate eddies and dead zones during use, optimizing the uniformity of the phosphating film thickness.

[0024] The liquid outlet guide plate 2 is installed via a rotating shaft 9 that passes through the immersion tank 1. Both ends of the rotating shaft 9 extend out of the sidewalls of the immersion tank 1, with one side housed in the bearing seat 8 and the other side connected to the control motor 10. During use, the angle of the liquid outlet guide plate 2 can be changed by rotating the rotating shaft 9, guiding the liquid sprayed by the spraying assembly 3 according to operational requirements and reducing the impact of the sprayed liquid on the liquid in the immersion tank 1.

[0025] The spraying assembly 3 includes multiple nozzles 11. The bottom of each nozzle 11 is connected to an upper liquid pipe 15, which is mounted on a mounting base 7. Below the mounting base 7 is a return liquid tank 5. The upper liquid pipe 15 extends downwards to the return liquid tank 5 to supply liquid to the nozzles 11. The return liquid tank 5 has an inlet 16 and an outlet pipe 12 connected to its side. The end of the outlet pipe 12 is connected to a lower liquid pipe 14, which communicates with the impregnation tank 1. Liquid is drained from the impregnation tank 1 through the lower liquid pipe 14. A control valve 13 is mounted on the outlet pipe 12 and is located in a maintenance slot 23 on the side of the impregnation tank 1. In use, the device sprays liquid through the nozzles 11, increasing the fluidity of the liquid in the tank. Small parts can also be coated using the spraying assembly area, making operation convenient.

[0026] The air-blowing structure 4 includes an air outlet pipe 19, an air inlet pipe 20, and an air-filling controller 21. Multiple rows of air outlet pipes 19 are arranged, with their bottoms connected to the air inlet pipes 20, which in turn connect to the air-filling controller 21. The air outlet pipes 19 of the air-blowing structure 4 are arranged on one side of the impregnation tank 1, opposite to the liquid spraying assembly 3. The air-blowing structure 4 generates gentle convection through microporous aeration (clean compressed air), improving the fluidity within the impregnation tank.

[0027] The impregnation tank 1 has a mixing structure 6 between the spraying assembly 3 and the air blowing structure 4. The mixing structure 6 includes a rotating shaft 17, a stirring rod 18, and a motor 22. The motor 22 is installed on the side wall of the impregnation tank 1. The rotating shaft 17 is connected to the bottom of the motor 22. The stirring rod 18 is connected to the bottom of the rotating shaft 17. The stirring rod 18 is attached to the inner bottom surface of the impregnation tank 1. The rotating shaft 17 is rotated by the motor 22, which drives the stirring rod 18 to rotate around the bottom of the rotating shaft 17.

[0028] When this device is in use, the liquid sprayed from the nozzle 11 changes its flow direction after passing through the liquid outlet guide plate 2 and enters the impregnation tank 1. The air blowing structure 4 generates gentle convection through microporous aeration (clean compressed air), which improves the fluidity of the impregnation tank 1. At the same time, the motor 22 controls the rotation of the rotating shaft 17, which drives the stirring rod 18 to rotate around the bottom of the rotating shaft 17, making the liquid in the impregnation tank 1 more uniform. This device guides the flow of liquid sprayed from the spraying component 3 through the liquid outlet guide plate 2, and generates gentle convection through microporous aeration through the air blowing structure 4, which improves the fluidity of the liquid in the tank. In addition, the mixing structure 6 is set up, which can eliminate eddies and dead zones during use and optimize the uniformity of the phosphating film thickness.
